vSphere Client must not have the Web Distributed Authoring (WebDAV) servlet installed.


Overview

Finding ID Version Rule ID IA Controls Severity
V-239756 VCFL-67-000015 SV-239756r679495_rule Medium
Description
WebDAV is an extension to the HTTP protocol that, when developed, was meant to allow users to create, change, and move documents on a server, typically a web server or web share. WebDAV is not widely used and has serious security concerns because it may allow clients to modify unauthorized files on the web server and must therefore be disabled. Because the WebDAV service has been found to have an excessive number of vulnerabilities, this servlet must not be installed. vSphere Client does not configure WebDAV by default.
